What this shows Qardio's Innovation Score is 25.4/100 (17th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Qardio?

Each dot is one of Qardio’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Qardio’s own 9.2 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qardio's grants concentrate

Qardio, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 40% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Qardio sits between Q-state Biosciences, Inc. and Qingdao Haier Innovation Technology Co., Ltd..

Qardio's three-year grant acceleration

Qardio, Inc. shows 1 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
